What is an all pass filter, and when do we use them?

WebThere are five basic filter types (bandpass, notch, low-pass, high-pass, and all-pass). The filter used in the example in the previous section was a bandpass. The number of possible bandpass response characteristics is infinite, but they all share the same basic form. Several examples of bandpass amplitude response curves are shown in Figure 5 ...
